Determine Cu+2 and SO4-2 concentration using Potentiometry?. I've been researching as well but all I could come close was solid state ion selective electrodes. Could someone please help me out?

There should be two methods(or one) to measure the concentrations.

Copper is easy - almost any cell containing copper electrode will do.

Not so easy with SO₄^2-. Perhaps Pb/PbSO₄ electrode could be used.
